The method will now return 0 on success and -1 on error, rather than number of items which it iterated over before it returned back to the caller. Since the only place where we actually check the number of elements iterated is in virhashtest, return value of 0 and -1 can be a pretty accurate hint that it iterated over all the items. However, if we really want to know the number of items iterated over (like virhashtest does), a counter has to be provided through opaque data to each iterator call. This patch adjusts return value of virHashForEach, refactors the body, so it returns as soon as one of the iterators fail and adjusts virhashtest to reflect these changes.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
